Fetal Heart Rate Monitor
Who qualifies for our non-for-profit pricing?


Moyo is a compact digital fetal monitor used during labor to help healthcare providers make timely, informed decisions by providing quick and accurate feedback on fetal heart rate.

Product contains lithium-ion battery.

*This product can not be shipped to the USA.

Timely and accurate monitoring

A 9-crystal sensor accurately detects the fetal heart rate (FHR) within seconds. Dual electrodes differentiate the maternal from the fetal heart rate, which differs from a regular doppler. Moyo can be used continuously or intermittently.

Better response to abnormalities during labor

Early detection of abnormal FHR guides decision-making and helps health workers to act quickly. A 30-minute histogram displays the FHR, and audio-visual alarm is activated if abnormal FHR is detected.

Confident health workers and happy mothers

Moyo is lightweight and portable — it can monitor continuously, even while the mother is moving around. It gives a longer heart rate history that informs health workers of the situation and eases the workload without interrupting existing routines.
